Title: Apparatus for measuring undersurface state using ultrasonic wave
Inventor: KAWAKAMI SHIGEYUKI
IPC: G01N29/04
Filed: 1989-10-11
Abstract: PURPOSE:To detect the flaw just under a surface with low frequency by irradiating an object to be inspected with a burst-like ultrasonic wave having length allowing the flaw echo and surface echo just under the surface to interfere with each other and detecting the level of the echo receiving signal obtained from the object to be inspected. CONSTITUTION:A transmission burst signal set to time length wherein a surface echo and the flaw echo obtained from the flaw under a surface is generated by a burst signal generating circuit 8 to drive a probe 1 and a part of the ultrasonic burst wave 9 generated from the probe 1 is reflected from the surface 2 of the object 3 to be inspected while a part thereof passes through the surface 2 to be reflected from the internal flaw 4 and both waves are respectively again received as the surface echo 9s and the flaw echo 9f by the probe 1. As a result, since the echo receiving signal of the interference wave synthesized by interference is obtained in a receiver 7, the presence of the flaw 4 of the object 3 to be inspected can be detected by detecting the peak level of the interference wave. At this time, when the generation length of the burst signal is changed, the position of the flaw can be also detected.

Title: Metal-hydrogen alkaline storage battery
Inventor: MATSUMOTO TAKANAO
IPC: H01M4/00
Filed: 1988-10-19
Abstract: PURPOSE:To enhance charge-discharge cycle performance and to increase high rate discharge performance after repeating charge-discharge cycles by increasing the amount of a binder in a hydrogen storage alloy layer on the surface of an electrode than its current collector side. CONSTITUTION:When an electrode is manufactured, the concentration of a binder in negative paste is decreased on the current collector side and that is increased on the electrode surface side so that the binder has concentration gradient in a hydrogen storage alloy layer. Movement of hydrogen storage alloy fine particles formed from current collector side to electrode surface side is retarded, and increase in binder concentration in the vicinity of a current collector can be retarded. Electric conductivity in the electrode is kept high, and high rate discharge performance after repeating charge discharge cycles is improved. Since the binder concentration on the surface of the electrode is high, coming off of hydrogen storage alloy powder existing on the electrode surface is retarded, and charge-discharge cycle performance is increased.

IPC: G11B5/65
Filed: 1994-10-28
Abstract: PURPOSE: To enable high density magnetic recording at a low cost as well as to ensure high coercive force by forming a nonmagnetic underlayer of an iron-based polycrystalline material contg. nitrogen and a magnetic layer of an iron-based material. CONSTITUTION: A magnetic layer 3 formed on a nonmagnetic underlayer 2 is made of an iron-based material.
